Letters Patent No. 85,037, dated December 15, 1868.

MACHINE .IE'QR MAKING PAPERCOIiLARS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom t ymay concer-n.-

Be it known that we, CHARLES SPOFFORD and CHARLES H. MONTAGUE, both ofBoston, in the county of Suffolk, and State of Massachusetts,.haveinvented certain Improvements in Machines for Making Paper Collars, oflwhich the following is 'a full, clear, and exact description, referencebeing had to the accompanying drawings, making part of thisvspecilication.

To `utilize a much larger percentage of the material employed than hasheretofore been accomplished, and to enable us to cut collars, cutis, orarticles in irregular shapes, and'to cut a greater number of the saidarticles in a given time, are among the objects of our invention, whichconsists of two or more pairs of cuttingdies, placed transversely acrossour machine, as shown in figs. 5 and.` 6, which, although they show onlythe regular-shaped collars, maybe of any irregular shapes desired, thusmeeting the present demands of the market for such goods, which demandcannot be met by any other machine now in existence, except by a much-lars or other articles may becut in any desired shape,

however irregular, by one operation of the machine.

And, again, the dies for cutting the projecting ends, in the machinesheretofore' used, heilig placed directly opposite each other, there is amuch greater amount of wastage at the two ends, which we obviate byarranging our dies transversely across our machine, one in advance ofthe other, so as to secin'e a proper and sufficient bearing for eachdie, and still out the paper without loss of material, which cannot bedone if the, ends of the dies are directly opposite each other, un-'less they are separated sulciently to secure the proper bearing, andthis separation necessarily involvesa heavy loss of material.

To illustrate, we would state that a good articleof linen-finishedpaper, used in the manufacture of collars, weighs about one hundredpounds to the ream, a ream being sudicient to cut five thousand collarsof the ordinary width.

To separate the points' of the dies one inch, which is the distancenecessary to stand the strain, would involve the loss of a strip ofpaper one inch in width-and thirteen thousand four hundred and fortyinches in length,` or about six and a halfpounds of paper, which, at thelowest market-price of forty cents per pound for finished papergvould bea loss of two dollars and sixty cents on every lot of five thousandcollars, or fifty-two cents per thousand, which is oflitsclf a faitprofit in the business.

To enable others skilled in the art to construct and use'our invention,we will proceed to describe the mauner in which we have carried itout.'A

Figure l is aplan or top view of a machine for making paper collars,with our improvements applied thereto.

Figure 2 is an elevation of one side of the same.

Figure 3 is an elevation of its opposite side.

Figure dis a section on the line x-x, iig. l.

Figure' 5 is a perspective view of a pair of male dies, arrangedaccording to our-improvements.

Figure 6 is a perspective view of a pair of female dies, arrangedaccording to our improvement.

Figures 7 and 8 are details, to be referred to in the followingdescription.

In the'drawings, A represents the frame of themachine, which isprovided, on each. side, with slots a b, lig. 4,-for the reception ofthe extremities oi' the heads B C, which slide vertically therein, theheadB carrying the male portions, c c, of the cutting-dies, each diecuttin g a'c`ollar at every downward motion of the lever G; and the headC, that of the embossing-dies, not shown.

c c are the femalev cutting-dies, secured to the framework, and throughwhich the collars fall, in a iinished condition, into a receptaclebelow.

These heads, B C, are connected by means of jointed rods, D E, with theleversG, one set on each side of the machine,V which are secured to ahorizontal shaft, H, having its bearings in the frame-work A.

The opposite ends of these levers G are pivoted' to the short arms, rl,projecting down from the straps e, of the ecccntrics I, which aresecured to the opposite ends of the shaft J, outside ofthe frame-work A,and by this means thelevers G are vibrated so as to impart the requiredvertical motion to the heads B C.

It willbe seen that the rods E, secured to the heads C, are pivoted tothe levers G atv a less distance from their fulcrum than the rods D, sothat more power is applied to the head C than tothe head B. Thus, byemploying two heads, arranged as described, and operating by diderentrods, attached to the same lever, at `unequal 'distances from the pivot,we secure an increased pressure upon the embossing-dies, greater thanthrough, as heretoforea very important consideration in the saving ofmaterial-and in' carrying the paper then4 steadily forward, still uncut,to the cutting-die or dies.

This arrangement of .the feed-roll between the heads B C, by which thepaper is drawn forward` after being embossed, also avoids thedifficulty, heretofore enc'onutered, in having the paper pushed throughthe embossing-dies, by which it was liable to double up and spoil theimitation-stitches, or other devices.

g 471, are two feed-rolls, which are placed between the two heads B andC, and revolve in movable boxes, ij, which slide vertically within slotsin the-frame-work A, the upper roll, y, being pressed down towards thelower one, 7i, by means of blocks, h, figs. 3 and 4, on the upper endsof which may be placed springs a, underneath the bars m.

The upper roll, which is driven by theflower one, is

connected thereto by means of gears o p, the shaft g,

ofthe lower roll, extending ont at one side beyond its box, j, where itis provided with a ratchet-wheel, K, securely keyed. thereto; and uponthe outer end of this shaft g is loosely fitted a gear, L, to the innerface of which is attached an arm, fr, carrying, at its outer end, apawl, s, which -engages with the -teeth of the wheel K, in contact withwhich it is retained by a flat spring, t. The arm r is vibrated so as toproduce an intermittent revolution of the wheel K and the feed-rolls, asrequired by the gear L, which is operated by a toothed segment, M, atthe upper end of a lever, N, which'is pivoted to a stud, fn, projectingfrom the flamework.

This segment is vibrated by means of a connectingrod, O, one extremity,9, fig.v 3, of which is secured to lever N, the opposite end beingpivoted to a crank-pin, l0, on the disk P, secured to the outer end ofthedriving-shaft J.

In order to regulate the vibration of lever N, with its toothed segmentM, and consequently the amount of feed, the end 9, of rod O, is securedto a sliding block, which is moved within a slot, w, in the lever N, bya screw, 1 and the distance from the filler-um of the' lever N to thepoint where the power is applied may thus be readily varied, as.desired, to increase or diminish the amount of feed at each revolutionof the diivingshaft. Q isa bifnrcated arm, which is secured to the endof a stud, a', and embraces the ratchet-wheel K, the inside ofthebifurcations being lined with felt or other suitable material, so as toproduce suleient friction upon the wheel to prevent it from beingrotated by the friction of the pawl s, it is vibrated in a contrarydirection. v y

Fig. 7 illustrates the appearance of `the paper after being cut with onedie on our machine as at present in use. Fig, 8 represents theappearance ofthe paper when eut by one or more pairs of dies by means ofour new improvement,

It will 'be observed that our improvements, as stated in our'secondclaims, are equally applicable to our machine, wliether one or morecutting-dies be used. By the use of our improvements, we are enabled tomanufaoturenearly one .hundred thousand more collars in ten -honrs thanany other machine now in use, and without any additional expense forlabor.

What we claim as our invention, and desire to secure by Letters Patent,is

The arrangement of the dies c c, with relation to each other,substantially as shown, and for the purpose set forth.

Also, the heads B O, arrangedas set forth, and oper ated by the lever G,to which they are attached at different points by the arms D E, oneactuating the cutting-die or dies, an d the other the embossing-dies,substantially as and for the purpose described.

Also, the feed-rolls g' h, when arranged as described, in combinationwith the heads BA C, substantially as and for the purpose' set forth.
